If there's a usb list this would be more appropriate in, please let me know.
I have a Toshiba PDR-M4 digital camera with USB interface, which appeared as a scsi device attached with usb-storage in linux-2.4.5, but hasn't worked in any kernel since then. Here's a snippet from dmesg from 2.4.5, with a successful negotiation with the camera (and its 128MB smart media card). The usbcore, usb-uhci, usb-storage, and sd modules are already loaded at this point.
usb-uhci.c: v1.251 Georg Acher, Deti Fliegl, Thomas Sailer, Roman Weissgaerber usb-uhci.c: USB Universal Host Controller Interface driver hub.c: USB new device connect on bus1/1, assigned device number 2 usb.c: USB device 2 (vend/prod 0x1132/0x4331) is not claimed by any active driver. Initializing USB Mass Storage driver... usb.c: registered new driver usb-storage usb-uhci.c: interrupt, status 2, frame# 1366 scsi0 : SCSI emulation for USB Mass Storage devices Vendor: TOSHIBA Model: PDR Rev: 1.00 Type: Direct-Access ANSI SCSI revision: 02 Detected scsi removable disk sda at scsi0, channel 0, id 0, lun 0 SCSI device sda: 256000 512-byte hdwr sectors (131 MB) sda: Write Protect is off /dev/scsi/host0/bus0/target0/lun0: p1 WARNING: USB Mass Storage data integrity not assured USB Mass Storage device found at 2 USB Mass Storage support registered.
And here's dmesg output from the same operation with 2.4.13:
* turn camera to 'data' mode * hub.c: port 2 connection change hub.c: port 2, portstatus 101, change 1, 12 Mb/s hub.c: port 2, portstatus 103, change 0, 12 Mb/s hub.c: USB new device connect on bus1/2, assigned device number 6 * 4-second pause * usb_control/bulk_msg: timeout usb.c: USB device not accepting new address=6 (error=-110) hub.c: port 2, portstatus 103, change 0, 12 Mb/s hub.c: USB new device connect on bus1/2, assigned device number 7 * 4-second pause * usb_control/bulk_msg: timeout usb.c: USB device not accepting new address=7 (error=-110)
And no more messages until I turn off or disconnect the camera. It never procedes to initialize usb-storage on this device.
The same errors ("usb_control/bulk_msg: timeout" and "USB device not accepting new address=7 (error=-110)") have occurred with every kernel since 2.4.6 when I attempt to attach this camera. I don't believe it ever worked with 2.2.18/.19 either, but it did work with 2.2.17 with Alan's usb patches.
